14 Claims.

This invention refers to package machinery and more particularly to adevice for placing seals of a shrinkin flexible nature around the tops,caps or closures of bottles and other containers. It has among itsobjects to provide a machine that will flow shrinking seal material andthe like used for sealing bottle caps and packages, on to the bottle,cut it off to a predetermined size and assist in the shrinking of thematerial. Another object is to provide for automatic feed of thematerial and the various steps for the placing of the material on thepackages. Its main purpose is to provide for a convenient, eflicient,and effective way of placing this material on the packages withoutmanual operation. A further object is to have the device so that it willreduce the hazards arising from handling the materials and the liquidsin which they are kept.

The present methods of placing the so-called flexible shrinking sealsover the caps of bottles and packages, where such seals are arranged toshrink tightly into place and over the caps and bottles, consist ingeneral in the following arrangement: The seals are individually cut tosize and then allowed to soak in a container full of formaldehyde,alcohol, or other suitable liquids or solutions, which are normally usedto keep the material from shrinking while in stock. They are taken outindividually by hand and placed over the bottle caps, wlL'ch they setover very loosely. They are then allowed to set and after about an hour,shrink sufliciently to tighten securely on the bottle and cap orwhatever package is used, as the solution evaporates from them. Thismaterial has to be picked up by the hands of the operator from itssolution which may enter the system of the person. In the work ofplacing the seals on the bottles, much time is occupied in opening theseals beforehand. In this invention there are no individual seals, butin their place of a tube of the material of suitable diameter is used.It is drawn up by fingers on the device and the solution is strained offback into the container as it passes up into the machine. The tube isforced onto the bottle neck and cap and when in place is cut off to suitthe bottle by a knife of the device, after which the machine blows airacross the seal to expedite its shrinking action.

Similar reference characters refer to similar parts throughout thedrawings.

In the drawings, l represents the legs of a metal frame on which a table2 is mounted and an under-tray 3 is secured. A pedal bar 4 is pivoted tothe frame with a pin 5 and serves to operate a clutch yoke 6 through alink bar 1, attached as indicated. A spring 8 attached to the undertray3 at 4 serves to keep a tension on the pedal bar. A tub container 9 isset on the undertray 3 to hold the tube of shrinking seal material It]used for the seals, as well as the liquid or solution for soaking thesame and keeping same normal size. This material is brought into theseal casing H which is bolted to the table 2 at l2, through its mouth l3which is preferably slotted at I4 and restricted by a flexible ring H4to strain the liquid or solution ofi the material as it is carriedthrough, and supports expanding cylindrical plunger 24. This casing haswall slots H5 to permit jaw members H6 to pass through and make contactwith the material I!) and allow 35 ample clearance. A cylindricalsliding sleeve l5 reciprocates on the outside Wall of the casing and hasa loosely mounted exterior collar l6 with a bevelled edge I l on itsupper portion, and cross pins IS on its peripheral wall for holdingoperating arms l9, to be described later. A screwthreaded stop-collar 20controls the downward movement of the collar IS. The jaw membermechanism is secured to the sleeve l5 and ful- 45 crumed on journals 2|and has adjusting screws 22 on extensions 23 to make contact with thebevellcd edge IT. This actuates the jaws with their rubber tips 99inwardly against the shrinking seal material as it passes over theexpanding cylindrical plunger 24. This plunger is vertically mounted inthe casing and is inserted in the shrinking seal tube as it progressestowards the bottle to be sealed. Springs 25 attached to the slidingsleeve l5 with screws 26 tend to keep the side of the table.

jaws out from the axis of the plunger to prevent pulling back the sealon the down stroke. The pressure upwardly exerted on the set screws 22(extensions, and jaw mechanism incidently) by the pressure of the edgeI'I against them, actuates the jaws to press on the seal material andraise same. The lower portion 21 of the plunger is tapered to insertinthe sealing tube gradually and thereby readily open the material withouttearing same.

The upper portion 28 is flat, preferably with chamfered edge I28 whilethe body in general is cylindrical. A narrow coverplate 29, preferablyof metal, is set flush in the table 2 above the plunger, knife andcasing and is provided with a seal orifice I02 for the tubular shrinkingseal tube to pass through to cover the neck of va bottle 30 and cap 3|for the sealing purpose. A knife 32 for cutting theshrinking-seal'material reciprocates in a slot 33 provided in the tableand the cutting edge is preferably in an angular direction so as to moresmoothly cut same. The table 2 is recessed for the cover-plate and knifeand has -a hole 34 for the tube material and plunger to operate in andpass through to the bottles or packages to be sealed.

The table has a hollow perforated ring 35 positioned around the bottleand cap where the seal is placed and rests on or is attached to thetable. It serves to convey air through its holes 36 to the seal after itis placed on the package and thereby expedite its shrinking in place.This perforated ring is supplied with air through suitable piping 31 andtank chamber 38 and source I38. The tank 38 is secured to the under- Thepiping is provided with a control valve 39 for opening and closing theline of piping, through a mechanism 40 and spring IIlI connected withthe operating arms I9 and collar I6.

The sliding sleeve I5 is raised as the bevelled surface ll of the collarI6 makes contact with the adjusting screws 22 and through the journals2| when the arms I9 raise the collar I6 through the cross-pins I8. Thesearms are pivoted at 4I to a stationary'arm 42 and pin 43 on the portionof the arm on the opposite side of the pivot which is engaged in a camwheel 44. The slots 45 and 46 respectively permit the pins I8 and 43 toactuate freely in the arms as the angularly arc-stroke of the arms I9reciprocates the collar I6.

The shaft 41 of the cam wheel is journaled at 48 in a hanger '49suspended from the lower surface of the table 2 by bolts 50. This camwheel is made in any suitable manner but preferably as indicated in thedrawings, in which a cam 5| is designed to give a quick reciprocatingmovement to its roller 52. The parts 53, 54 and 55 are recessed into themain casting as indicated and secured in place with screws 56. The slot51 with its grooves 58 is arranged to permit a cross-head 59 and the pin"43 held byit to be adjustable in the same.

A cam-throw adjusting lead screw 60 is arranged in the cam wheel withits collar 6| set in the parts 53 and 54 to hold it in place, and permitsame being turned at its head 62 for raising the cross head or loweringit, in the slot. Calibrations 64 for setting same in a predeterminedmanner for controlling the movement of the arms I9, are provided asshown.

The cam wheel has its shaft 41 attached to a conventional clutch member65 which engages with its separated but corresponding member 66 whenmoved over by the yoke 6 actuated by the link bar I. This allows a motor68, through its shaft connections and speed reducer 61 and the member66, to rotate the member 65. The motor 68 is suitably supported by astructure 69 to the table 2 on its underside.

The roller 52 is attached to a rod I8 that in turn is guided on thetable 2 and holds the knife 32, and has a horizontal reciprocatingmovement, the return stroke being controlled by a coil spring 1| securedto a stationary hook I2 attached to the table.

A series of posts I3 of rectangular cross section are verticallypositioned on the upper portion of the table. They are provided withsleeves 74 that slide thereon and keep directional control of same aswell as adjustably secure arms 11, I9, 8I, 83 that have plates designedto hold the bottle or package to be sealed, securely in place. Setscrews I6 serve to hold arms and sleeves in any selected place. A coilspring I8 tensions the plate 86 with its rubber bumper 82 on its holdingbolt 84, the latter having an adjustable collar 86 for preventingexcessive movement. The arms I9 have plates 81 with rubber bumpers 88while the arms -8I have plates and rubber bumpers 89. The rear post isprovided with an arm 83 which has a plate 90 and rubber bumper 9|. Allthese plates and bumpers serve to hold the bottle or package securelywhile being sealed, and permit same being readily held or detachedtherefrom.

An automatic release mechanism for controlling the continuous orindividual cycle operation of the machine consisting of a finger II9,rods 93, 94, guides 96 and a tripping pawl is provided to periodicallystop the feeding arrangement of the device. The pawl 95 consists of anoutward end I95, actuated upwardly by a spring 395, and an inward end295 actuating downwardly retaining the pedal 4 in a locked position, forone continuous cycle, after which the treadle 4 will be releasedautomatically, unless the treadle 4 is engaged by catch 91, in whichevent the machine will continue to operate continuously until releasedby pressing down extension 98 so it will place catch 91 out of registrywith treadle 4, a spring I60 attached to a supporting bar I58 tensionsthe extension 98 with its catch'9I as indicated.

The machine is provided with a counter :I06 attached conveniently tothe'table and actuated by the rod I0, so as to indicate each cycle. Theshrinking seal material is laidin the tub in layers or like a coil ofrope. The material is composed of ingredients made under specialformulae and may soak or rest in formaldehyde, alcohol, ether, and othersuitable solutions tending to keep the material enlarged and unshrunken. One suitable material on the commercial market is known as'Sylphseal.

The operation of the machine is as follows:-

The operator slides the shrinking seal tubing into the casing I II andaround or over the plunger 24 which opens the tubing up and makes itpass upwardly in a cylindrical tubular form until it reaches the cap andbottle. The machine is then started by throwing in the clutch and motorconnections and circuit 92, and the cam 'wheel '44 is turned, which inturn operates the arms I9 and causes the loose collar I6 to movevertically up and down. On its upward movement, the bevelled edge I'Icomes in contact with the adjusting screws 22, forcing same upwardly torotate the jaw members I I6 so their rubber tips press against the sealtubing. As the jaws move upwardly their rubber or resilient tips 99carry the seal tubing upwardly also. While this is occurring the plunger24 will slip by its weight through the incoming sealtubing entering thecasing through its mouth at I4. The incoming tubing will be strained ofliquid as it presses between the tapered end 27 and against therestricted sides of the casing and the excess solution carried up willdrain down through the slots at I4 back to the tub 9.

The seal tubing, as it covers the cap and bottle, will be sheared off bythe movement of the knife 32, and will stay on by its natural stickinessor resiliency. Then, as the air from the ring 35 will be freed by theoperation of the valve 39 through the mechanism 40, its action willevaporate the liquids on the shrinking seal and cause it to shrink withits clamping or tightening action. Just sufiicient seal tubing issheared off to seal the bottle and its cap, the size or length of theseal is predetermined by suitably setting the cross-head in its slot, byturning the screw 60. This screw may be turned by using a screw-driverin the slot in its head. The arrows on the drawing show the direction ofrotation of parts of the machine. The cam-wheel in rotating carries thepin 43 around with it and in turn raises and lowers the arm I9 on thecam-wheel side of the pivot M. The arm I9 on the opposite side of thepivot raises and lowers oppositely, and will proceed to raise the collarI6 by pressing on the cross-pins I8. This collar slides over the sleeveI5 which it diametrically surrounds, until the bevelled surface I!presses against the end portions of the screws 22, which have beenadjusted to operate at a predetermined point of the cycle. Theextensions holding the screws are rotated on the pivots 2I and in turnrotate the jaws with their rubber or resilient tips 99 towards the sealtubing until they press against same, the plunger 24 serving to providesufiicient resistance in back of the seal tubing to enable it to betightly engaged by these jaws without raising the plunger. On furtherupward movement of the collar, and the sleeve and jaw mechanism withsame, the tubing is pushed upwardly towards the cap and bottle throughthe orifice in the table, until it is placed around the cap and bottle.At the same time the valve 39 is opened and allows air or othershrinking medium to blow against the seal. The cam 5I is also pushingthe knife against the tubing, through its contact with the roller 52,the rod I0 and the holder I03 holding the knife. After the knife haswith its angular edge I32 sheared through the shrinking-seal tubing, andleft the cut off portion over the neck of the bottle and cap, itretreats, due to the pulling action of the coil spring II and the shapeof the cam following against the roller 52. The cut-off shrinking sealbegins shrinking and fastens on the bottle and cap sufficiently topermit it to stay in place and allow the removal of the bottle and theplacing of another in the holder plates and pumpers. The cam-wheelcontinues rotating and carrying the pin 43 around, with the arms I9returning the stroke of the collar and allowing the casing to lower andloosen its jaws on the tubing and slide down over same. The knifereturns out of the way and the air or other mediiun is turned off fromthe ring 35. At the end of each single cycle the arm I9 and finger I I9strike the rods 93 and moving end I95 of pawl 95 downwardly, compressingspring 395, the end 295 moving upwardly to such a position as to releasethe treadle 4. If it is desired to operate the machine continuouslywithout stopping at the end of each cycle, the treadle 4 may bedepressed downwardly towards the left so it will engage with the catch91. In this position the pawl 95 will not be engaged and the machinewill operate until the catch 9! is released manually from the treadle 4.In either instance the treadle 4 will be returned to its upward restposition through the tension of the coil spring 8, which raises the linkI and shifts the clutch to disconnect the machine from the source ofpower, or motor 68.

The operation is repeated after the new bottle and cap are placed in theholder. The operation of the holders does not appear to require furtherelucidation.

In its operation, the seal tubing is held in the casing by therestricted mouth ring H4 and the clamping action of the weightedplungers tapered head against its interior. This prevents the tubingfalling back into the tub container. This weight also offers suflicientresistance to enable the tube to be frictionally engaged by the jaws andopened out from its flat natural form. It also stretches it somewhat,lessening the amount required and bringing about a quicker shrinking.The air or .other'evaporation reduces the time of shrinking considerablyand thereby increases the rate of production over present methods. orother parts of the body avoids the possibility of actual contact withthe material or solution and its absorbing action into the system of theoperator and consequent danger to his well-being, is a materialadvantage that this device provides. It saves the liquids and solutionsby draining the excess back into the tub container. The device enablestubing of shrinkingseal material to be used in considerable lengths,that can be readily taken up by the machine, which is not only cheaperbut avoids the difficulties of picking out individual seals that maystick together in twos and threes and in inconvenient ways.

It should be noted that the bottles or packages are preferably held inan inverted position while being sealed, preventing the excess liquidfrom running over and destroying the bottle labels, etc. The function ofthe bevelled edge I! is to enable the jaw mechanism to be operated moreeffectively as it will take up the tilt of the levers on this surfacereadily. The counter is operated in a conventional manner at the end ofthe cycle by the rod III. The slots H5 in the casing I5 are large enoughto permit the jaw members and tips 99 to slide easily along and in same.The various adjustments do not seem to require detailed explanation butsuch do allow for the variation of the stroke of the arms I9; themovement of the knife, the action of the jaw members, and otherincidental connections and parts. The cover plate is removable and thestop collar permits a slight adjustment. The construction is relativelysimple and permits accessibility to its parts and eliminates complicatedmovements.

While but one form of the construction of this invention is shown in thedrawings, it is not desired to limit this invention to this particularform, or in any other way otherwise than limited by the prior art, as itis appreciated that other forms could be used using the same principlesand coming within the scope of the appended claims.
